"If you really wanted to hide yourself completely, you could always run away and join the circus," Watson offered unhelpfully.
Holmes frowned. "I possess no skills that would be useful in a circus," he huffed, "and if this is your way of insinuating my acting skills would make me a good clown, then I swear I shall take offense."
"I assure you that I meant no offense at all, and I strongly disagree with your assertion that you have no skills that would be useful in a circus. You can bend iron pokers with your bare hands, perform baritsu against opponents double your weight, your deductions already sound like magic, and you could easily learn to throw swords, blow fire, or perform on the trapeze. Really, Holmes, you're the perfect all-around circus performer."
Holmes rubbed his chin thoughtfully. "I suppose you're right," he conceded, "it would be a shame to throw my talents into cheap entertainment, but for a few months of incognito work it might make for an amusing distraction. Will you be my trapeze partner, Watson?"
"I have a bad shoulder, Holmes. I wouldn't last one second on a trapeze."
"Well, well, that's that then. If my loyal Watson cannot be by my side, I see no point in pursuing any alternate profession, no matter what it may be."
For the prompt from mrspencil: circus skills.
